摘要：

Plots of monthly median noon time foF2 values at Manila, Kodaikanal and Vanimo vs solar EUV flux (170-190 angstrom), smoothed sunspot number R12 and smoothed solar radio noise (10.7 cm) flux indicate saturation effects in the foF2 vs sunspot plots. The saturation diminishes in the foF2 vs solar radio noise plots and disappears for foF2 vs solar EUV plots. Thus, in the absence of EUV data, solar radio noise could be a reasonably good substitute, better than sunspots, for predicting foF2 values on time scales of one month, or more.
